Presently I use Bitwarden (with a selfhosted Vaultwarden backend) for this reason, and block the phone-home spyware the Bitwarden people ship in the client with DNS blackholing.
Happy to replace it if: a) there is an import path from Bitwarden and b) a good client for iOS that supports the native iOS password manager APIs. I expect further enshittification from Bitwarden in the future, and keep a close eye on new projects like this one as a result.
